Own price elasticity formula
In contrast, when the quantity demanded does not change much, we say demand is inelastic. In contrast, when the price of the product you want to buy rises high, you might look for alternatives. But, we use different prices to calculate both. When the price rises, the effect on income depends on how much it decreases the quantity demanded. We calculate the own-price elasticity of demand by dividing the percentage change in quantity demanded of an item by the percentage change in price.
4.1 Calculating Elasticity
The two types of demand elasticity are:. Whereas in other cases, price increases reduce revenue. An increase in price decreases the quantity demanded, and in contrast, a reduction in price increases the quantity demanded. Finally, when faced with unitary elastic demand, price increases will not change total revenue. A decrease in quantity demanded will compensate for the rise in price by an equal percentage.
So, when companies increase their prices, customers will switch to alternative products. When you see an alternative at a more affordable price, you will, of course, buy it. It is elastic or responsive when a slight change in price causes a more significant change to the quantity demanded. Consumers consider the price of buying products.
When companies face an elastic demand curve, a slight increase in price reduces the quantity demanded larger. For example, how much change the quantity demanded of coffee when its price rises.
Key points
As a result, price increases, reduce total revenue. Please remember. Here is the mathematical formula:. The effect of price elasticity on total revenue assumes other factors are unchanged.
Cross-price elasticity tells us how responsive coffee demand is when the price of tea changes. Low prices allow you to shop more. Both concepts are the same, i. In contrast, when demand is inelastic, rising prices will increase total revenue. When car prices go up, how significant is the impact on changes in gasoline demand? It depends on the elasticity of demand for the product. Meanwhile, cross-price elasticity uses the price of related products, which can be a substitute or complementary.
Consumers are unresponsive to the price increases. Own-price elasticity of demand measures how responsive demand is when the price of goods changes. Demand elasticity is a measure of the responsiveness of changes in demand when prices change. Raising prices does not always increase company revenue.
Thus, demand will only change small. The next example is gasoline demand and car prices. Knowing the elasticity of demand helps companies to set prices. Own-price elasticity uses the price of the product itself. Sometimes, a higher price does not translate into higher revenue. Also, the effect only applies to necessities. Meanwhile, for luxury goods, price increases will increase demand and company revenues.
When you purchase food products, what do you think first?
Because the price is not the only determinant of revenue. Remember, demand has an inverse relationship with prices. Both complement each other. Remember, revenue is a function of quantity demanded and price.
